Feeder driver happy with pay

When discussing contract with feeder driver yesterday, he said he is happy with pay and will vote yes, but only concern is part timers leaving union. Well no kidding idiot if you pay the part timers catch up raise they will be happy like you and have reason to stay. No catch up raise for existing part timers has the most potential to damage the union of anything in this contract. And it matters to full timers just as much in big picture.
